- (IBAction)jsonSystemButtonDidClicked:(UIButton *)sender {    self.JSONArray = [NSMutableArray array];    // 1、拿到 json 文件的路径    NSString *path = [[NSBundle mainBundle] pathForResource:@"student" ofType:@"json"];    // 2、根据路径获取文件内容为 NSData 对象    NSData *data = [NSData dataWithContentsOfFile:path];    // 3、解析开始    NSArray *array = [NSJSONSerialization JSONObjectWithData:data options:(NSJSONReadingMutableContainers) error:nil];    for (NSDictionary *dict in array) {        StudentModal *modal = [StudentModal new];        [modal setValuesForKeysWithDictionary:dict];        [self.JSONArray addObject:modal];    }    for (StudentModal *modal in self.JSONArray) {        NSLog(@"JSONArray = %@, %ld, %@", modal.name, modal.number, modal.hobby);    }}

@property (nonatomic, strong) NSMutableArray *JSONArray;

当模型中类型冲突时

@implementation StudentModal- (NSString *)description{    return [NSString stringWithFormat:@"%@, %@, %@, %ld, %@", self.name, self.sex,self.phoneNumber, self.number, self.hobby            ];}- (void)setValue:(id)value forKey:(NSString *)key{    // super 必须写    [super setValue:value forKey:key];    if ([key isEqualToString:@"number"]) {        self.number = [value integerValue];    }}
